유다정,박귀근 한국산업식품공학회 2019 산업 식품공학 Vol.23 No.1

β-mannanase from Trichoderma reesei was purified by DEAE Sephadex A-50 ion exchange chromatography and Sephadex G-100 gel chromatography. The molecular weight was determined to be 54 kDa by tricine SDS-PAGE. Trigonella foenum-graecum galactomannan was hydrolyzed by the purified β-mannanase, and then the hydrolysates were separated by Bio-Gel P2 chromatography. The main hydrolysates were composed of D.P. (degree of polymerization) 2, 3, and 4, 6 galactomanno-oligosaccharides. To investigate the effects of Trigonella foenum-graecum galactomanno- oligosaccharides on in vitro growth of L. plantarum, were cultivated individually on a modified-MRS medium containing carbon sources such as low- and high-molecular-weight galactomanno-oligosaccharide. Lactobacillus plantarum grew 1.8-fold after treatment with high- and low-molecular-weight galactomanno-oligosaccharides, compared to 1.3-fold for those with standard MRS medium. Bacteriocin was purified by Sephadex G-100 gel chromatography and determined to be 122 kDa by tricine SDS-PAGE. The bacteriocin activated doubly more effectively after treatment with galactosmanno-oligosaccharides compared to those with standard MRS medium. Bacteriocin showed antimicrobial activity against Staphylococcus aureus. The inhibitory compound lost activity when heated to temperatures greater than 30oC and when inhibited to pH changes that lowered the pH below 4 or raised it above 5. Furthermore, its effects were inhibited by treatment with proteolytic enzymes.

In the “4.2.1 Alarm and Evacuation Facility for the Visually and Hearing Impaired” category of Barrier Free certification jointly operated by the Ministry of Health and Welfare and the Ministry of Land, Infrastructure and Transport, visual alarms installed in toilets must be installed in a well-visible location. However, there is no clear evaluation criteria for the location of the visual alarm in the bathroom, so it relies on the subjective judgment of the evaluator. Therefore, in this study, we would like to present a clear evaluation method for the location of the toilet visual alarm required by the obstacle-free living environment certification.

Objectives: The main purpose of this study was to examine the direct and indirect effects of co-parenting, infants’ emotional self-control, and infants’ externalized problem behaviors. Methods: A total of 281 mothers of infants aged 3-5 years responded to questionnaires on three research variables. The scale used in this study was first measured using a co-parenting questionnaire, the emotional regulation checklist (ECR), and the child behavior checklist (CBCL). Data were analyzed with structural equation modeling using SPSS 21.0 and AMOS 20.0. Results: The correlations between co-parenting, infants’ emotional self-control, and externalized problem behaviors were all statistically significant. With regard to the direct impact of co-parenting on infant problem behavior, co-parenting had a significant impact on infant externalized problem behavior. Co-parenting also indirectly influenced the externalized problem behaviors in infants through the infants’ emotional self-control. Conclusion: This study demonstrated the importance of co-parenting and infant’s emotional self-control. The results suggest the need for a parent education program to improve infants’ emotional self-control and could be used as basic data for counseling and parent education sites to develop parenting programs to prevent infant problem behavior and ultimately create an enviroment that positively affects infant development.

홍대 앞 버스킹 문제 해소를 위한 커뮤니티 서비스 디자인

홍대 지역은 흔히 ‘젊음, 자유로움, 개성``을 떠올리게 하는 곳이다. 2000년대 중반부터 급격한 상업화를 겪었으며, 최근엔 관광지로 유명해져 명실상부한 서울의 주요 상권으로 자리 잡았다. 젠트리피케이션(Gentrification)의 영향으로 과거의 이색적인 모습은 많이 사라졌지만, 아직까지 홍대 앞의‘걷고 싶은 거리’에서는 거리 공연들을 쉽게 볼 수 있고, 주말이면 이를 구경하는 사람들로 인산인해를 이룬다. 하지만 홍대가 생활 기반인 이들에게 버스킹은 상권 침해나 소음을 비롯한 피해를 유발하는 골칫거리다. 그리고 이에 대한 적절한 법적, 행정적 규제가 아직 이루어지지 않고 있다. 본 연구는 모바일 커뮤니티 기반의 서비스 디자인을 제안하며, 궁극적으로 지역사회와 공존하는 버스킹 문화를 지향한다. 따라서 관찰 조사, 심층 인터뷰, 이해관계자 모델링 등 UX 방법론을 통해 홍대 앞 버스킹의 현황 및 문제점들을 분석했다. 이후 프로토타이핑과 사용성 테스트를 단계별로 실시하여 현 버스킹 문제를 개선하는 서비스를 기획, 디자인하고, 검증했다. 결과적으로 본 연구가 국내 버스킹 실태에 대한 이해, 버스커들의 자정적 노력과 함께하는 버스킹 문화의 발전에 기여할 것으로 기대한다. Hongdae reminds us of youth, freedom, and uniqueness. Since the mid 2000s, it has become really commercialized and be famous for its tourist attraction and larg shopping area. Even though gentrification affected to change original, interesting places, we can see busking easily on Hongdae walking street until now. The street crowded with people who enjoy it every weekend. Busking is a great sightworthy show for people visiting Hongdae. Even though it causes infringement of commercial supremacy and noises for residents of Hongdae, the authority has enforced neither legal nor administrative regulation appropriately. The objective of this study is to solve those community problems incurred by immature busking performances. This study proposes a service design based on mobile community function, pursuing positive busking culture coexisting with local society. This study also diagnosed current situation of busking in Hongdae through field observation, contextual inquiry, affinity diagram and modeling. The service for improving busking problems was designed and verified with phased prototyping and usability test. As a result, it can contribute to understanding current Korean busking reality, and development of busking culture with self-purification by buskers.

청소년의 공감이 도덕적 이탈과 도덕적 분노를 통해 친사회적 행동과 반사회적 행동에 미치는 영향

한세영,유다정 한국생활과학회 2023 한국생활과학회지 Vol.32 No.2

이 연구의 목적은 공감과 친사회적/반사회적 행동의 관계에서 도덕적 분노와 도덕적 이탈의 매개적 역할을 알아보고자 하였다. 참가자들은 온라인 설문조사를 통해 489명의 청소년(16~18세)이었다. 청소년들은 공감, 도덕적 이탈, 도덕적 분노, 친사회적, 반사회적 행동에 대한 설문에 응답했다. 수집된 데이터는 구조방정식 모델링으로 분석하였다. 그 결과 공감은 도덕적 분노와 도덕적 이탈을 통해 친사회적 행동과 반사회적 행동에 간접적으로 영향을 미치는 것으로 나타났다. 공감은 도덕적 분노를 증가시키고 도덕적 이탈을 감소시켜 친사회적 행동을 촉진하고 반사회적 행동을 감소시켰다. 공감의 직접적인 영향은 친사회적 행동에만 유의하고 반사회적 행동에는 유의하지 않았다. 본 연구의 결과는 청소년 공감과 도덕적 행동 사이의 관계를 이해하기 위해 도덕적 이탈과 같은 인지 과정과 도덕적 분노와 같은 감정적 과정을 모두 고려해야 함을 보여준다. 또한 공감에 의해 유발되는 도덕적 분노가 친사회적 행동을 촉진하고 반사회적 행동을 감소시킨다는 것을 발견했을 때 도덕 발달 연구에서 도덕적 분노를 긍정적 도덕 감정으로 재고해야 함을 시사한다.

청소년의 인지적 · 정서적 공감과 이타행동이 심리적 안녕감에 미치는 영향

한세영,유다정 한국아동학회 2024 아동학회지 Vol.45 No.1

Objectives: This study sought to determine the mediating effect of altruism behavior in the relationship between cognitive and emotional empathy of adolescents affecting psychological well-being. In order to improve adolescents’ psychological well-being, which is a time when they experience rapid changes emotionally and physically, useful information on factors that affect psychological well-being can be provided. Methods: The subjects of the study were 282 teenagers aged 16 to 18 living across the country (136 men and 146 women) through online survey companies. Adolescents responded to questions on empathy, altruism, and psychological well-being. The collected data used Pearson's right-rate correlation analysis and structural equation models using SPSS 22.0 and AMOS 23.0 programs. After that, the statistical significance of the mediating effect was confirmed using the direct and indirect effect verification and bootstrapping method between variables. Results: The main findings are as follows. First, analysis of the correlation between research variables revealed a static correlation between emotional empathy and altruism behavior, altruism behavior and cognitive empathy, and psychological well-being and altruism. Next, as a result of examining the structural path between research variables, cognitive empathy and emotional empathy showed a significant correlation with altruistic behavior, and altruistic behavior showed a significant correlation with psychological wellbeing. Finally, cognitive empathy and emotional empathy influenced psychological well-being through altruistic behavior. Conclusion: Adolescents’ cognitive and emotional empathy affect psychological well-being through altruistic behavior. These results indicate that both cognitive and emotional empathy are not only helpful to others, but also play an important role in one’s own psychological adaptation and well-being. Adolescents not only express sympathy and empathy, but also pay attention to others’ feelings, which can become a factor that can actually lead to actions for others; furthermore, such actions can improve the happiness of individual adolescents. These findings revealed efforts to understand and sympathize with others is meaningful to enhance the happiness of ordinary adolescents in public education sites where competition is overheated, and happiness is reduced.
